milky bellflower

Requires a fertile, moist but well-drained, neutral to alkaline soil in sun or partial shade. The delicate flower colour is best preserved in partial shade. The plants may require staking in exposed positions

Cut back after flowering to prevent self-seeding and to encourage a second flush of flowers

Propagate by seed in containers in a cold frame in spring. The plants will self seed, if allowed to do so and produce plants with some colour variation. Divide clumps in spring or early autumn. Take stem-tip cuttings from new growth after flowering

Vulnerable to slugs and snails

Powdery mildews and a rust may be problematic
